摘要
以不同年龄、不同密度的落叶松(Larix gmelini)人工林为研究对象,基于标准地37株标准木的树干解析、枝解析的生物量数据,研究胸径、树高、冠幅等指标与单木各分量(树干、枝、叶)生物量之间的关系,通过统计分析建立了落叶松单木各部分生物量的回归模型,为了解落叶松人工林生产力,并对其进行合理经营提供了科学依据。
Taking Larix gmelini plantations with different densities at different ages as research objects , based on the biomass analysis of tree stem analysis and branch analysis for 37 standard trees, relationship among the indices （DBH, tree height, crown） and each component （stem, branch, leaf） were studied. Establishing regression model of biomass of the single tree for each part of Larix gmelini by using statistical analysis can not only understand productivity of Larix gmelini plantation , but also provide a scientific bas is for its rational management.
